WebThe moment of intertia of the first point is i1 = 0 (as the distance from the axis is 0). Of the second point: i2 = m (L/2)^2 = mL^2/4. Of the third point: i3 = mL^2. The total moment of … WebThe moment of inertia is a physical quantity which describes how easily a body can be rotated about a given axis. It is a rotational analogue of mass, which describes an object's resistance to translational motion. …

WebMoment of Inertia. We defined the moment of inertia I of an object to be [latex]I=\sum _{i}{m}_{i}{r}_{i}^{2}[/latex] for all the point masses that make up the object. Because r is the distance to the axis of rotation from each piece of mass that makes up the object, the moment of inertia for any object depends on the chosen axis. To see this, let’s take a … WebMoment of Inertia is a physical quantity that resist to transitional motion. It's the angular esistance to keep the stationary object stationary and moving object moving, mathematically derived from the sum of products … dms chola ms
